Error CXX0069 variable needs stack frame

[munteanu24d]

Hi !

I have this function which i use in order to traverse a quadtree :

void SPMG::traverse(qNode* node ,qNode* trav[] , int& size) {
  
	if(node != NULL ) {
		
	        traverse(node->child[0],trav,size);
			traverse(node->child[1],trav,size);
			traverse(node->child[2],trav,size);
			traverse(node->child[3],trav,size);
			trav[size++] = node ; 
	}
}

I call if from another function :

void SPMG::merge(qNode* rootNode ){
    	
    
	 int size = 0;
	 qNode* trav[1000];

	 traverse(rootNode ,trav ,size);	  
}

;

And i get the following error : CXX0069 variable needs stack frame .

I have read that this error may be caused by variables declared as part of an inline function . Which might be right in my case , because i declare qNode* trav[] vector in merge function , before to call traverse .

Where should i declare the qNode* trav[] vector ?
I tried to declare it as extern within the class and i get an external unlink error (error LNK2001: unresolved external symbol "class qNode * * trav" ).


Thanks in advance ,
D.M.

Which line is the error pointing at?

[munteanu24d]

  void SPMG::traverse(qNode* node ,qNode* trav[] , int& size)

At this line of code , but only at the second iterartion of the function .

And i get the following error : CXX0069 variable needs stack frame .

This is a message from the debugger, and is not a compiler or linker error.

Given that it is a debugger message, are you going to change your code so as to make the debugger accept it? If so, that is the wrong approach to writing a program, as you're design is being controlled by what the debugger accepts.
